United States Patent 19 Claims. Cl. 234-5) The present invention concerns typesetting machines like those known by the trade name Linotype machines,

and more particularly that portion of such machines in which a recording device e.g. a perforator is provided for recording e.g. by producing coded perforations in a tape indications representing first of all different characters to be typeset and secondly, if characters of different styles or from different fonts are to be used in the typesetting operation, also indications representing the particular selected different styles or fonts. A machine of the contemplated type also comprises a totalizer arrangement for totalizing the matrix-widths corresponding to each of the various characters to be type-set so as to obtain in this manner during the operation of the machine a signal whena typeset-line is ready for justifica-tion. In order to supply the totalizer with information concerning the matrix-width of each individual character a character to-matrix-width translator arrangement is provided which translates mechanically or electrically a signal or other information representing a particular character into a signal or other information rep resenting the matrix-width applying to that particular character so that this latter information can be supplied to the totalizer. If in the typesetting machine different styles of characters or fonts are to be used selectively or alternatively during typesetting operations, then a plurality of such character-to-matrixavidth translators must be provided each being assigned to a particular font provided that the different fonts to be used alternatively differ from each other insofar as at least one character occurring in the different fonts is associated with different matriX widt-hs, respectively. It is well known that the recording of information representing the individual characters and representing the selected font e.g. by means of coded perforations of the tape are used further on for controlling the mtarix assembling and slug casting sections of the typesetting machine.

Character-to-matrix-lwidth translators are known in the art and consist for instance of mechanical or electrical counting storages or registers. These devices may contain a store of individual elements corresponding to the matrix-widths of the characters constituting a particular font. Upon actuation of a control'device e.g. a key- 0 erable switch actuating the perforator for producing a perforation corresponding to the particular character, simultaneously an indication corresponding to the width of the corresponding matrix is furnished from the translator device to the totalizer which in conventional man ner controls an indicator indicating that portion of the entire length of a line to be typeset which is occupied by the sum of matrix-widths selected up to a given moment and thus indicates also how much more space or line length is available in the particular line.

Of course, the translator device may be constructed also in a different manner, eg. as .a terminal board having input terminals respectively assigned to different characters and having output terminals assigned to different matrix-widths so that by proper interconnection of individual input terminals with selected output terminals the desired translation is carried out. In a similar manner banks of such input terminals and banks of such "ice output terminals may be connected selectively by interposing punched cards establishing the desired particular connections across the punched holes.

Ordinarily, each font requires a corresponding translator device. However, in certain cases fonts representing different styles of characters may still be handled with one particular translator device provided that all the characters of one font have the same matrix-widths, respectively, .as the corresponding characters in the other font.

If it is desired that the character recording e.g. a perforated tape be used for controlling the operation of a typeset-tin machine operating alternatively with one of two fonts or out of four fonts then usually a cor-responding number of translator devices must be provided of which, one is to be rendered operative when operation with one selected font is to be started i.e. when a recording e.g. a perforation is produced which indicates that the operation is to be switched from one font to another font.

An arrangement is known in which upon a change between fonts the corresponding translator device e.g. a mechanical counting storage or register must be exchanged manually against another one corresponding to the font to be used after the change. This has to be done every time after the indication of a change from one font to another has been recorded e.g. by producing a corresponding coded perforation in the control tape. When the operation with the new font is to be switched back to operation with the previously used font the above procedure has to be repeated in reverse order.

In another known arrangement in which the translator device is an electrical apparatus a plurality of such electrical translators .are present in the machine. In order to switch from the operation with one font and with one translator device to another one or for rendering one or the other of these electrical translator devices operative a selector switch is provided which may be arranged at the front .Wall of the housing of the perforator. Also in this case the typing operation, i.e. the actuation of the character keys on the key-board must be interrupted before or after the indication of the change from one font to another has been recorded e.g. by the production of a corresponding coded perforation of the tape, and then the above-mentioned control switch must be set to a position corresponding to that translator device which is now to be used during the ensuing typesetting operation.

It has been found that all these known arrangements entail serious disadvantages. The changes from one font to another may occur during the typesetting of one line. During such an operation the attention of the operator is distracted from the manuscript because he has to stop typing and has to operate the above-mentioned control switch or has to manually exchange the mechanical translator device. Generally, the danger exists that the operator simply forgets to actuate the control or selector switch .or to exchange the mechanical translator. In any case the handling of a separate device for changing from one font to another greatly slows down the typesetting operation.

It is therefore one object of this invention to provide for an arrangement of the type set forth in which the recording of a change from one font to another or of the particular selected font is produced simultaneously with the selection of the corresponding translator device by operation of one single font selector member associated with the particular selected font.

It is another object of the invention to provide for means assisting the operator in recognizing whether he has carried out properly the desired or required change snsaeoa from one font to another which may be achieved e.g. by providing for the production of a signal which may be a visible one for indicating the particular font selection.

It is still another object of this invention to provide for an arrangement of the type set forth which is comparatively very simple in structure and reliable in operation.

With above objects in view the invention includes a combined recording and matrix-Width arrangement for type-setting machines, comprising, in combination, a recording arrangement including recording means for recordin g indications representing different selected styles of characters to be typeset and different indications representing respectively different characters to be typeset, and including a plurality of actuating means respectively associated with different characters and adapted to actuate the recording means, a totalizer arrangement including a totalizer for totalizing the matrix-widths corresponding to each of the various characters to be typeset and including a plurality of character-to-width translator means also associated with each of the actuating means and adapted when activated to transmit from the actuated actuator means to the totalizer a specific matrix-width indication associated with a particular one of the translator means and with a particular character of a selected style, and a plurality of selector means associated, on one hand, with the translator means, respectively, and, on the other hand, with the recording means, each individual selector means when actuated activating selectively one of the translator means and simultaneously causing the recording means to record an indication representing the selected translator means whereby the style of the characters to be recorded during activation of the particular selected translator means is determined.

It will be seen that by an arrangement according to the invention a change from one font to another in no way interferes with the current typing operation. The manual exchange of one mechanical translator against another at the time when operation has to switch from one font to another is entirely avoided. Since one actuation of a selector device causes simultaneously the change from one translator device to another and causes the recording of an indication of such change it is entirely impossible that, as was the case in the prior art, one or the other of these two operations is carried out alone while the other one is inadvertently omitted.

It is a particular advantage that in an arrangement according to the invention the font selector member can also be constructed as a key-operated switch the key of which may be arranged within the area of the characterdetermining actuator keys of a keyboard whereby the operation is greatly facilitated.

Another advantage of such an arrangement is that the operator does not have to carry out in the case of a necessary change fron one font to another a movement of his hand which would distract his attention from the manuscript while in the known arrangement a separate control switch or member had to be actuated which was located remote from the key-board, e.g. at the front wall of the housing of the perforator. If as mentioned the font selector keys are arranged within the general key-board the actuation of the font selector keys can be carried out by the operator in an extremely simple manner since the operation of these font selector keys can be made a part of the normal ten-finger key-board operation.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of speciflc embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 is a schematic block diagram illustrating the interrelation of the components of the so-callcd perforator section of a typesetting machine including the invention;

FIG. 2 composed of FIGS. 2a and 2b, is a schematic circuit diagram of an arrangement according to the invention as applied to a typesetting machine operating with four translator devices;

FIG. 3 is a partial circuit diagram illustrating a modification of only one portion of the arrangement according to FIG. 2 in an adaptation for a typesetting machine operating alternatively with two fonts out of four available fonts and including pre-selector means; and

PKG. 4 is a partial circuit diagram illustrating another modification of a portion of the arrangement of FIG. 2 in an adaptation to a typesetting machine operating alternatively with two fonts out of four available fonts and including pre-selector means for selecting a particular pair of fonts.

Referring to the diagram of FIG. 1, it can be seen that the perforator section of the typesetting machine (not shown) is controlled from a combined control section composed of a key-board 1 and a control board 2. It will be shown further below that the key and control boards 1 and 2 contain the key-operated actuator switches corresponding to the characters to be typeset and the front selector switches for selecting a particular font, and, in certain modifications of the invention, also a font preselector switches which are also key-operated. If desired, the control board 2 may also comprise a signal means eg telltale lamps indicating which font has been selected in a particular phase of the typesetting operation.

Both the key-board 1 and the control board 2 are connected with a coding device 3 of conventional type for converting signals or control pulses furnished by the keyoperated switches thereof into a perforation code so that correspondingly coded pulse combinations are transmitted to the actual perforator 4 of conventional type which will therefore produce corresponding recordings in the form of coded perforations on the control tape 5, the code being preferably based on a system comprising at least six code elements. Thus, any operation or actuation of any one of the key-operated switches in the keyor control boards 1, 2 will cause the perforator 4 to produce a corresponding recording on the tape 5.

Both the key-board 1 and the control board 2 are additionally connected with a distributor matrix 7 which may be an electrical matrix and which serves to distribute signals received from the boards 1 or 2 among the plurality of character-to-matriX-width translators or counting registers 8 to 8 Theoretically the number of these translators is not limited and for the purpose of explaining this invention four translators are shown, each being associated with a different font to be used in the typesetting operation.

As will be explained further below in reference to FIG. 2, the above-mentioned translator devices are in their simplest form a multiple terminal or plug board whose input terminals are respectively connected via the distributor matrix 7 with the different actuating key-operated switches corresponding to different characters, respectively, and located in the key-board 1, while the different output terminals correspond respectively to different matrixwidths applying in one or the other font to the respective characters. The character-to-matrix-width translation is effected simply by connecting, in each of the translators assigned to a particular font the individual character pulse input terminals with those of the output terminals which correspond to the matrix-Width applying in that particular font to the respective character. However,

the translator devices may also be of a different type as for instance, a type including record carrier and read-out means, or a type in which banks of input and output terminals may be combined conductively with each other in a selective manner by interposing punched cards or perforated tapes.

The pulses appearing at the output terminals of the individual translators 8; to 8 and representing matrixwidths are transmitted to the totalizer 11, preferably in coded form via a coding matrix 9 wherein the just mentioned output pulses are converted into coded information suitable to be processed by the counting and adding devices in the totalizer ll. Ordinarily, the conventional totalizer 11 is equipped also with indicating means, not shown in the drawing, for indicating when a line composed of a certain number of matrices is ready for justification.

It should be borne in mind that in the above described arrangement the actuation of any one of the character keys in the key-board 1 has the effect that simultaneously in the recording means e.g. the perforator 4 a recording is produced e.g. by coded perforations on the control tape 5 representing the particular character corresponding to the actuated key, and also corresponding matrix-width information concerning the particular character is transmitted to the totalizer 11.

Since the width of at least some characters occurring in different fonts to be used in a typesetting machine differ from each other it is necessary that in the perforator section thereof which produces records or tape-perforations for the control of the pertaining multi-font matrix assembling and slug casting section a plurality of interchangeable translator devices are provided by means of which during the operation with a particular font the correct matrix-width information is transmitted to the totalizer ll. It is a characteristic feature of this invention that the selection of the translator to be used is effected simultaneously with the actuation of the perforator 4 for producing a recording or coded perforation indicating the change from one font to another.

FIG. 2 is a circuit diagram illustrating an arrangement according to the invention permitting the selection of any one of e.g. four character-to-matrix-width translators S to S for the ensuing typesetting operation.

A key-board 1 contains a set of character key-operable switches of which for the sake of clarity of the drawing only the keys T T and T are shown, each adapted to actuate a respectively associated actuator switch S S and S In this embodiment the key-board 1 also comprises font selector keys T T and T respectively associated with font selector switches 12, 13 and 14. In this example the just-mentioned actuator and selector switches are normally open switches and are all connected at one terminal with a bus bar 15 carrying positive potential. Additionally the key-board 1 contains in this example a further main font selector key T associated with a normally open switch 16 which has one terminal connected via line 66 with a source of positive potential.

The normally not engaged contact-s of the above-mentioned actuator and selector switches are connected respectively with junction points it? to 23 which are respectively connected by lines 25 to 31 directly with the perforation coder 3. Thus, Whenever one of the keys T T T I to 'I or T is actuated an actuating pulse is applied correspondingly to the perforator 4 not shown in PEG. 2.

However, there are, of course, in reality many more input lines like 32-34 because one such line must be provided for each character key in the key-board 1. For the same reason, there are in reality correspondingly more output lines like 32 32 33 43 34 -34 Again, similarly each of the translators ti -8 has a corresponding number of input terminals of which corresponding to the actuator keys T T and T only three are shown as indicated e.g. in the translator 8 at 37 for the character A at 37 for the character B and at 37 for the character X. This feature is the same in the other translators as can be seen from FIG. 2.

'Each of the transistors 8 -8 is provided with a series of output terminals 33 to 38 the numerical suffix and the numerals along the inbetween output contacts indicating the association of these individual output terminals with respectively different matrix-widths. Of

6 course, the number of these output contacts -is arbitrary and depends only on the number of different matrix-o widths that has to be taken into consideration in the typesetting and justification operations. All those output contacts 38 -38 of the four translators 8 -8 which are associated with the same matrix-width are connected with each other by connectors 40 -40 as shown and each of these individual connecting lines are connected at a junction point with the corresponding one of the translator output lines 41 -41 respectively. It is clear,

that each of these translator output lines-is again associated with one particular matrix-width so that each of these output lines will carry when energized a signal or pulse characteristic of a particular matrix-width.

For coordinating different character types with the appropriate matrix-width thereof the simple embodiment illustrated by FIG. 2 provides for corresponding wire connections 39 between the above-mentioned input and output terminals of the individual translators ti -8 For instance, in the translator 8 which may be assigned to a font I both the input terminals 37 assigned to the character A and the input terminal 37 assigned to the letter X are connected with the output terminal 38 because in the font I both the characters A and X may call for the same matrix-width to which corresponds the output terminal 38 However the input terminal 37 assigned to the letter B is connected to the output terminal 38 which corresponds to a different matrix-width. As can be seen the connections between input and output terminals are different in the translators 8 and 8 as signed to other fonts II and III, respectively, because in these other fonts the matrix-width of the respective characters differs from those applying to font I. One should not be surprised that the connections between input and output terminals in the translator 8 is the same as in the translator 8 Although the translator 8 is as-' signed to to a different font IV this may only mean that the font 1V differs from the font III in style e.g. one having standard characters and the other having italic characters, the matrix-width applying at least to the characters A, B and X occurring in both fonts may be identical.

The coding matrix 9 is of conventional type and does not form part of this invention so that a detailed description appears to be unnecessary. In this matrix the matrix-width representing pulses supplied through the output lines 41 to 41 to the matrix inputs. 42 to 42 are converted into coded signals which are then applied in a circuit comprising column lines 43, rectifiers 45 and load resistors 44 to the respective input terminals of the totalizer 11 which is conventional and therefore not further described.

It will be shown further below that at any given moment only one of the character-to-matrix-width translators 8 to 8 can be in operative condition. Therefore, it will be understood that upon actuation of any one of the character keys in the key-board I, not only, as described above, a corresponding perforation is produced in the control tape 5, but also, depending upon which one of the translators is in operative condition, a signal is transmitted through the coding matrix 9 to the totalizer 11 so as to represent in each particular case the matrixwidth applying to the respective character in the particular font which is to be used in accordance with the opera tiveness of the translator associated with that particular selected font.

The selection of a font to be used in the ensuing typesetting operation i.e. the selection of the particular translator to be rendered operative accordingly, is effected by actuation of aparticular one of the font selector keys T T or T as the case may be.

For this purpose connecting lines 49, 5t), 51 and 24 are taken respectively from the above-mentioned junction points 2043 to junction points 46, 47, 43 and 60 respectively. Across these junction points connection can be established between the font selector switches 12-16 and a combination of relays having solenoid coils M and N, respectively, for operating relay contacts m to m and I1 and n respectively. Relay coils or solenoids M and N are connected via resistors 61 and 62 with a source of negative potential.

The energizing circuits of the relay coils M and N comprise junction points 63, 64 and 65, 67 respectively. The junction point 63 is connected via diodes 52 and 53 with the juction points 46 and 48 while the junction point 64 is connected via the diodes 54 and 55 with the junction points 47 and 60. The junction point 65 in the energizing circuit of the relay coil N is connected via the diodes 56 with the junction point 46 and via diode 59 with the junction point 47. The other junction point 67 in the energizing circuit of the relay coil N is connected via the diodes 57 and 58 with the junction points 48 and 60. The relay contacts m associated with the relay coil M and the relay contacts 11 associated with the relay coil N are connected as self-holding contacts for keeping the respective coils energized after the application thereto of an energizing pulse.

In the distributor matrix 7 each of the lines 32 -32 33 -33 and 34 -34 is provided with a branch line 63 terminating in a diode 69. Of these branch lines 68 groups are formed in such a manner that the lines 68 of each group are branched off those main lines of the matrix 7 which lead to a different translator, respectively. For instance, the group of branch lines 68 connected with a control line 70 are branched off from the lines 32 33;, and 34;. The branch lines 68 connected to control line 71 are branched off from the main lines 32 33 and 34 The arrangement of the other groups of branch lines 68 connected to control lines 72 and 73, respectively is analogous.

The group control lines 7%) and 71 are taken to two stationary contacts of the change-over type relay contact m while the group control lines 72 and 73 are similarly taken to the stationary contacts of another changeover type relay contact 211 Since the four group control lines 70-73 correspond to the four translators S to 8 it is clear that if the number of these translators is increased, the number of the group control hues and of the relays and relay contacts would have to be increased correspondingly. In any case, the relay contacts m and 111 are connected respectively to the stationary contacts of another change-over type relay contact 11 which is at its other end connected to a source of positive potential.

Secondary control lines 74-77 are branched off from the control lines 70-73, respectively, as shown. The secondary control lines 74-77 are all connected to negative potential and preferably includes a signal or telltale lamp 78 to 78 respectively which, as will be explained further below, indicate when energized which font has been selected and accordingly which one of the translators 8 to 8 has been rendered operative. In the present examples the secondary control lines 74-77 are taken to the different translators 8 -8 respectively, and are connected therethrough with negative potential. The effect of the secondary control lines 74-77 connected to negative potential is that all those of the control lines 70-73 which are not connected to positive potential by one or more of the relay contacts m n 112 are bound to carry negative potential. Therefore, the diodes 69 mentioned above are connected as shown with their output terminals to the control lines 70-73.

It should not be overlooked that the above mentioned connections 28-31 serve the purpose that when any one of the font selector keys T -T or T is actuated and thereby the associated font selector switches 12-16 are closed, a pulse is applied through the perforation coder 3 to the perforator 4 for producing on the control tape 5 a correspondingly coded perforation indicating either that a change between fonts is desired or more particularly c: which particular font out of a plurality thereof has been selected for the ensuing typesetting operation.

Now the operation of the arrangement according to FIG. 2 will be described. In the drawing the arrangement is shown with all components being in idle position. As can be seen, in the idle or normal position of the relay contacts 11 m and 111 the control lines 71-73 carry negative potential while only the group control line 70 is connected to positive potential. Under these conditions the signal lamp 78 is energized so as to indicate that now only the translator 8 is in operative condition. This is in fact the case because the negative potential carried by the control lines 71-73 applies across the diodes 69 also to the matrix lines 32 -32 331F331, and 3411-3341 Th6 resulting effect will be explained further below.

It now one of the character keys T T or T of the key-board 1 is actuated and the respectively associated actuator switch S S or 8;; is closed, then positive potential is applied from the bus bar 15 to the respective one of the junction points 17-19. Consequently, first of all, such positive potential is transmitted as a pulse via the respective branch lines -27 to the perforation coder 3 and thus to the perforator 4 so as to cause the latter to produce a perforation corresponding to the character assigned to the actuated character key.

On the other hand, if for instance the character key T of the key-board 1 has been actuated and the associated actuator switch S has been closed, then such positive potential is applied also to the input line 32 of the matrix 7. Since under the assumed circumstances mentioned above the position of the relay contacts n m and 111 causes all the control iines 71-73 to carry negative potential with the exclusion of the control line 76, only the matrix line 32 carries no negative potential while the lines 32 32 do carry a negative potential. Consequently, the positive potential from bus bar 15 and closed switch S can reach via line 32 and the respective diode 36 the input terminal 37 of the translator 8 The resulting pulse representing in this example the character A is now transmitted through the respective connection 39 to the output terminal 38 from where it continues as a pulse now representing the matrix-width applying to the character A in the selected font I and further transmitted via line 40 and output line 41 to the corresponding matrix line 46 of the coding matrix 9. As a result the input line 43 leading to the totalizer 11 will be energized in a well known manner so that the totaiizer 11 will now process by adding or counting the received information concerning the matrix-width of the just introduced character A. The operation in the case of actuation of a different character key on the key-board 1 would be quite analogous.

As has been mentioned above, under the given circumstances the distributor matrix lines connected with the control lines 71-73, e.g. the matrix lines 32 32 and 32 carry negative potential on account of the connection of the control lines 71-73 via signal lamps 78 -78 to negative potential, so that the positive potential applied from the junction point 17 to the lines 32 32 and 32 is consumed by the respective input resistors 35. Consequently, a positive potential upon closing of the switch S cannot reach the input terminals 37 37 and 37 of the translators 3 -8 This will be better understood if one considers that for this purpose the value of the load resistors 44 of the totalizer 11 is comparatively large relative to the resistance value of the individual input resistors 35, and, in turn, the resistance value of each input resistor is comparatively large relative to the resistance of the individual signal lamps 78. In addition, the resistance in current-passing direction of the diode 69 is smaller than or not more than in the order of, that of the individual signal lamp 78, while the resistance in blocking direction of the diodes 69 is large relative to the resistance of the individual load resistor 44.

It may be mentioned at this point that the distributor matrix 7 as shown and described may be very well replaced by other means for distributing the actuating pulses among the translators. For instance, an arrangement of relays may be used.

From the above it should be clear that under the described circumstances i.e. with the normal position of the relay contacts 11 m and m or in other words when the relay coils M and N are not energized by actuation of any one of the font selector keys, only the translator 8; is in operative condition so that now any actuating and character representing pulses resulting from actuation of any one of the actuator switches S -S are transmitted to the perforation coder 3 but otherwise only to the translator 8; and from the output .terminals thereof in the above described manner to the coding matrix 9 and to the totalizer 11. i

It now for the purpose of switching to a different font and for rendering operative a difierent one of the translators 8 -8 one of the font selector keys T -T in the key-board 1 is actuated then the translator 8 is rendered inoperative and a selected one of the other translators is rendered operative. It may be assumed that the font selector key T is actuated so as to close the font selector switch 13. This has the effect that positive potential from the bus bar 15 is applied to the junction point 21 and from there via line 29 to the perforation coder 3 so that the perforator 4 is caused to produce a coded perforation indicating the change to a different font or more particularly the selection of font III to which the translator 8 is assigned. However, simultaneously said positive potential is applied from the junction point 21 via line 50 and junction point 47 to the diodes 54 and 59. The positive potential appearing at the diode 54 is consumed via junction point 64 and resistor 61. Hereby the relay coil M is short-circuited so that the relay contact m m and m would return to their illustrated normal position provided that in a preceding operation the relay coil M had been energized and kept in this condition by the closed holding contact m On the other hand, the positive potential of junction point 47 is applied via diode 59 to the junction point 65, whereby the relay coil N is energized. After application of the resulting energizing pulse the relay coil N is kept in energized condition by the now closed holding contact 21 Simultaneously, however, the energization of the relay coil N has caused the change-over relay contact n to move to its second position so as to apply positive potential to the control line 72. This results for the same reasons stated above in the first example of operation in rendering only the translator 8 operative. The signal lamp 78 is now connected through line 76 with negative potential so as to be energized and to indicate that now the translator 8 is in operative condition.

If now one of the character keys T T of the key board 1 is actuated the positive potential of the bus bar 15 is applied via the respective junction point 17, 18 or 19 through one of the lines -27 to the perforation coder 3 and consequently to the perforator 4, and simultaneously it is also applied via the respective one of the matrix input lines 3244 to the matrix 7. In the same manner as described above out of the matrix lines 32 -32 313 33 and S i -34 only that one thereof will permit passage of said positive potential through the respective diode 36 to the matrix output lines which is connected via one of the diodes 69 with the now positive group control line 72. The group control lines 70, 71 and 73 carry negative potential. Consequently, all the character representing pulses produced by closing of one of the actuator switches S S or S can reach only the translator 3 As can be seen from FIG. 2, and described above, the interconnections between the input and output terminals of this translator 8 are arranged differently from the arrangement of the connection lines 39 in the translator 8; so that now in connection with the characters selected by. the actuation of the character keys different informa- 16 tion concerning the respective matrix-widths is furnished to the totalizer 11.

In a similar manner actuation of the font selector key T i.e. closing of the associated font selector switch 14 results in energization of both relay coils M and N via the diodes 53 and 56, respectively. Both relay coils are kept in energized condition in view of the closing of their associated holding contacts m and m The relay contacts. n m and m are all moved to their respective second positions whereby positive potential is applied only to the group control line 73. In the manner set forth 'above, the signal lamp 78 is energized and the translator 8 is rendered operative.

The consequence of actuation of the font selector key T is quite analogous and will be understood without further detailed explanations.

If after actuation of any one of the above described font selector key T -T the main font selector key T is actuated and the associated switch 16 is closed, then a positive impulse from line 66 is applied via line 83, junction point 23 and line 31 to the perforationcoder 3 whereby the perforator 4 is caused to produce a perforation indicating change of font or change to another translator. In addition, the relay coils M and N are simultaneously short-circuited via the diodes 55 and 5'7. Consequently all relay contacts return to their original or normal position whereby now again the starting condition is re-established which means that now again only the translator 8 is in operative condition.

It is evident that the arrangement as illustrated in principle by FIG. 2 can be modified so as. to apply also to a machine equipped with more than four translators 3. For all practical purposes this will be rarely needed because the conventional typesetting machines are not equipped with more than four such translators or counting registers. It is generally known to operate an arrangement comprising four translators in such a manner that out of the four translators two are pre-selected so that during the typesetting operation alternatively types can be used from one or the other font in connection with the use of one or the other translator.

FIG. 3 illustrates a modification of the portion 2' of the arrangement according to FIG. 2. The modified portion 2:: as shown by FIG. 3 is designed for pro-selecting one pair of translators out of a total of four available translators. In operation actuation of the above-described rnai-n font selector key T results in selection of one of the two pro-selected translators and causes simultaneously the perforator to produce a coded perforation of the control tape 5 indicating the change from one translator to the other, i.e. from one font to the other.

The general arrangement according to FIG. 2 remains in this embodiment unchanged except that the font selector keys T -T may be omitted and that the portion 2' of FIG. 2 is replaced by the portion 2a of FIG. 3. Those components which are the same in FIGS. 2 and 3 carry the same reference numerals.

According to FIG. 3 the group control lines 70-73 are not only connected via the signal lamps 73 -78 with the negative lines 7447, respectively, but also with lines 79-82, respectively, which are connected with a first group of pro-selector switches -85 and a second group of pro-selector switches 1S5 respectively, the individual switches of these two groups being actuatable respectively by pre-selector keys 84 84 Each of the above mentioned groups of pro-selector switches is connected in the form of a first and a second cascade arrangernent, respectively, the sequence of the individual switches in one cascade being opposite to that in the other cascade, as illustrated. The input ends of the two cascades of switches (at the left-hand end as seen in FIG. 3) are connected with the stationary contacts of a changeover type relay contact 111 of a relay having a relay coil M so that the abovernentioned ends of the two cascades may be connected alternatively with a source of positive potential. The operation of this particular arrangement will be described further below. The lines 66 and 83 coming from the selector switch 16 operated by the main font selector key T are taken to the change-over type relay contacts 11 and n associated with the relay coil N. The relay contact 12 connects in its normal position the line 66 with one terminal of the relay coil N and with the relay contact 111 and in a second position with a line 33. The relay contact 11;, connects the line 83 in one of its positions with a line 96 connected to negative potential, and in its second position with the positive terminal of the source. In addition, the above-mentioned normally open contact 111 is arranged between the relay coils M and N. Finally a combination of relay contacts m and n is provided between the positive terminal of the circuit and the control line 31 which leads to the perforation coder 3.

FIG. 3 illustrates a portion 2a of the general arrangement according to the invention, the portion 2a being a modification of the corresponding portion 2 of FIG. 2. In this modification, the selection or activation of the translator arrangements 8 -8 is effected by the main font selector key T however, font pro-selector keys 84 -84 are provided for pro-selecting two out of the four translators. In normal or starting condition of the arrangement none of the translators fi -8 is in operative condition. However, if for instance one pair of translators S S are to be preselected for use in the ensuing typesetting operation, then the pro-selector keys 84 and M are actuated whereby the res ectively associated pro-selector switches 85; and 85 as well as 185; and 185 are moved from their re spective normal positions, as shown, to their respective second positions. As can be seen, the two groups of preselector switches are each connected in cascade arrangement, the input ends of the two cascades being respectively connected with the stationary terminals of a changeover relay switch m The individual pre-selector switches mentioned above, when moved to operative position, establish connection with a corresponding one of the auxiliary control lines 7982, respectively, as will be described further below. As can be seen in the tarting condition, the relay contact m in its normal position applies positive potential to the upper switch cascade 85 -85 and since the pre-selector key 84 has been actuated, this positive potential is applied via switch 85 to the auxiliary control line 79. Consequently, the signal lamp 78 is energized and via group control line 70 all those lines of the matrix 7 which are connected with the translator 8 are subject to the effect of positive potential at the diodes 69 connected with line 7 t), as described above, so that the other translators S S are rendered inoperative. However, in the same manner the translator 8 is rendered operative due to the fact that by the actuation of the preselector key 84 the pro-selector switch 185 has been prepared for being rendered also operative. Nevertheless, while translator 8 is in operative condition the translator 8 still remains inoperative. It should be noted that only for the purpose of clarity of the drawing the individual pre-selector switches 84 84 have been shown twice in FIG. 3, it being understood that, e.g. the ke 84; simultaneously operates the pre-selector switches S and 185 and so on. In the present example, the movement of the pre-selector switches 85 and 135 to their respective second positions has no effect on the described operation.

After the translator 8; has been activated as just described, the typesetting operation may be carried out in the normal manner using the font associated with the translator 8;.

Whenever it is now desired to switch to font IV and correspondingly to activate the translator 8 the main font selector key T is actuated whereby the switch 16 is closed. Hereby the relay coil M is energized, the energizing circuit being as follows: from the negative terminal in FIG. 3 via line 90, change-over relay contact 11 line 83, switch 16, line 66, change-over relay contact 12 and relay coil M to the positive terminal. Consequently, relay coil M is energized and moves the relay contacts "1 and m, from their illustrated normal position to their respective second position. The contact m in its second position causes application of positive potential through line 86 to the input end of the lower switch cascade. At the same time positive potential is removed from the group control line 70 so that the latter is supplied with negative potential through the line 74, while now positive potential is applied to the group con trol line 73 via the pre-selector switch 185 in its operative position and auxiliary line 82. As a result, the signal lamp 73 is energized and in the same manner as described above all those lines of the matrix 7 which are connected with the control line 73 are subject to the effect of the positive potential therein and are enabled to carry character representing pulses to the translator 8 while all other translators are now in inoperative condition. In addition, upon actuation of the main font selector key T a positive impulse is applied via the relay contact m moved to its second position and the relay contact 11 in normal condition and from there through line 31 to the perforation coder 3 as described above whereby the perforator 4 is caused to produce a perforation in the control tape 5 indicating change of font.

During the actuation of the main font selector key T and energization of relay coil M also the relay contact m has been moved to closed position. Consequently, after the key T has been released and switch 16 has returned to open position, the relay coils M and N are connected in series and the coil N is energized and remains so. The relay contacts 11 and :1 move to their second position which however has no further effect at this moment because, as stated above, switch 16 is now in open position. However, the relay contact 11 has also been moved to its second position so that positive potential is now removed from line 31.

The entire arrangement is now in condition for proceeding with the typesetting operation by using the font IV and the translator 8 If at a given moment it is desired to return to the use of font I and translator 8 the main font selector key T is again actuated. Hereby the following circuit is established for energizing the relay coil N: from the positive terminal in FIG. 3 via relay contact n line 83, closed switch 16, line 66, relay contact n line 88 and relay coil N to the negative terminal. Since the relay contact m is still in closed position the relay coil M is now short-circuited and consequently de-energized. As a result, the relay contact m returns to its original position so that again positive potential is applied to the input end of the upper cascade of preselector switches 85 Line 82 is disconnected from the source of positive potential so that now the control line 73 is again supplied with negative potential from line 77 while new line 79 again applies positive potential from switch 85 to the control line '70. Consequently, the signal lamp 78; is again energized and the translator 8 again activated, as described above.

At the same time, the relay contact 111 is returned to open position and the contact in, is returned to its first position so that a positive control pulse is applied via the contact 11 still in its second position to the control line 31 to the perforation coder 3 whereby the perforator 4 is again caused to produce a perforation indicating change of font.

It will be understood that certain fonts represent different styles of characters but do not differ from each other as far as the width of corresponding matrices is concerned, e.g. a font in semi-bold style and a font in italic style. In conventional arrangements two different translator devices have been used for such different fonts. However, with an arrangement according to the invention, operation is possible with only one translator for use with potential is applied as described above both such fonts. In such a case for instance after actuation of the pre-selector key 84 the pro-selector switch 85 would connect the line 80 with the normally engaged stationary contact of the relay switch m while simultaneously the pro-selector switch 185 would connect the same line 80 with the other stationary contact of the relay switch m Consequently, every time when the main font selector key T is actuated and accordingly a perforation is produced indicating change of font, the line 80 isconnected with positive potential whereby due to positive potential in control line 71 all the lines of the matrix 7 leading to the translator 8 are rendered capable of carrying character representing pulses. If it should be desirable to provide also in this case for a signal indicating which one of the two fonts now associated both with the translator 8 is in use, a further signal lamp 87 may be provided which would be energized by an addi tional relay contact m FIG. 4 illustrates a further modification of the invention, the portion 2b illustrated therein being a modification of the portion 2 of FIG. 2. In the lower portion of FIG. 4 again two groups of pre-selector switches 101 -101 and Mil -Mu respectively, are shown as being connected in cascade arrangement. In the same manner as described above corresponding switches of both groups are actuated by pro-selector keys ree respectively, shown twice in the diagram only for the purpose of clarity of the drawing. This pre-selector arrangement is so constructed that the actuation of any one of the pro-selector keys IN -136 causes pre-selection of a different pair of translators selected from four translators 8 8 In the left lower corner of FIG. 4, a chart illustrates this effect of the operation of the pre-selector switches.

According to FIG. 4, lines 1692 to 105 are provided which may be supplied with positive potential depending upon the positions of the respectively associated pre-selector switches Mil -101 and 201 201 Depending upon energization or not of a relay coil R, the change-over type relay contact r operated thereby positive potential is applied either to the upper cascade Hil -191 or to the lower cascade fil -201 For instance, if the pre-selector key 109 is actuated the pre-selector switches 101 and 201 are moved to their respective second position whereby first of all the line 102 is supplied with positive potential from relay contact r in its normal position, while a circuit for line 103 is only prepared but not yet closed.

The line 102 is connected with the group control line 70 so that in the manner described above only the translator 8 is activated and the signal lamp 78 is energized. The

'line 103 is connected with the group control line '71 so that whenever positive potential is applied later to the line 103 the translator 8 can be activated.

105 to be supplied with positive potential. As can be seen easily in this manner by the actuation of the key 100 (in accordance with the above-mentioned chartlthe translators 8 and 8 are pro-selected for being used.

The selection of one of the two pre-selected fonts or translators is effected only by actuation of the main font elector key T but may also be eifected by actuating either the key T or the key T as will be described. In circuit with the switch 16 operable by the key T is connected the relay coil R in series with a diode 1% and a resistor 107 so that the coil R is energized when the switch 16 is closed. However, in circuit with the switch 12 of the font selector key T a further diode 1% is provided which is connected in parallel with the relay coil R and in series with the resistor 107.

If, e.g@ the pre-selector key 1%; is actuated, positive via line 102 to translator 8 is changed to the the group control line 79 whereby the activated. If now operation should be pro-selector keys 84 -34 order to coordinate the operation of the perforat or and of the matrix assembling and slug casting section of the other pro-selected translator 8 the main font selector key T is actuated. Hereby positive potential is applied via line 66, closed switch 16 and line 83 to the relay coil R. This coil is energized and holds itself in this con dition by means of the holding relay contact r The relay contact r is moved to its second position so that now positive potential is applied via the pre-selector switch 201; to the line 103 and from there to the group control line 71 whereby the translator 8 is activated and signal lamp 73 is energized. The pulse energizing the relay coil R is simultaneously delivered from line 83 via line 31 to the perforation coder 3 whereby the perforator 4 is caused to produce a corresponding perforation in the control tape 5 indicating which translator or font has been selected.

If it is now desired to return to the previously used font or translator, the font selector key T may be acto open position so that now the entire arrangement ac cording to FIG. 4 is returned to its starting condition. However, upon actuation of the key T a control pulse has been applied also via line 313 (FIG. 2) to the perforation coder 3 so as to cause the perforator 4 to produce a perforation indicating which font or translator is now selected and prepared for being used.

It will be understood that in a similar manner the same effects as described above will be obtained analogously by actuation of any other ones of the pre-selector keys ree The arrangement just described may be modified in a further manner, not illustrated, by providing for actuation by each of the pre-selector keys -100 a further normal open contact, respectively, which is so constructed and connected With the perforation coder 3 that upon actuation of any one of the pre-selector keys 100 -190 a pulse is applied to the perforation coder 3 so as to cause a corresponding perforation in the control tape 5 indicating which pair of translators or fonts has been pro-selected.

Finally, it may be mentioned that the cascades of preselector switches are so arranged in relation to each other,

as illustrated, that for instance after actuation of any one of the pre-selector keys Nth-109 at the start of the typesetting operation always that one of the translators 8 which is designated by the lowest sufiix I to VI is in operative condition. The same applies to the arrangement according to FIG. 3 with respect to the actuation of the This is of importance in setting operation that matrix magazine corresponding to the pre-selected fonts must be in operative position which corresponds to the translator 8 designated with the lowest suffix number.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of a combined recording typesetter machine and matrix-width totalizer arrangement differing from the types described above.

While the invention has been illustrated and described as embodied in an arrangement for selectively controlling the typesetting machine adapted to set type from more than one font, it is not intended to be limited to the the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for vari- 15 ous applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
